  Synthesis and Unusual Chemical Reactivity of Certain Novel 4,5-Disubstituted 7-Benzylpyrrolo[2,3-d][1,2,3]triazines

  摘要：

  The fact that only two pyrrolo[2,3-d] [1,2,3]triazines heterocycles had been reported in the literature prompted us to initiate studies designed to provide additional members of this ring system. Initial attempts to prepare additional derivatives of the 7-unsubstituted pyrrolo[2,3-d] [1,2,3]triazin-4-ones were limited by their low chemical reactivity. Subsequently, 7-benzyl-5-carboxamidopyrrololo-,3-d] [1,2,3]triazin-4-one (16) was prepared from diethyl 2-nitropyrrole-3,4,-dicarboxylate via an alkylation, ammonolysis, reduction and intramolecular diazocoupling sequence. Conversion of 16 into 7-benzyl-4-( 1,2,4-triazol-1-yl)pyrrolo [2,3-d] [1,2,3]triazine-5-carbonitrile (17) was accomplished, and nucleophilic displacements of the 4-triazol-1- yl group were studied. Treatment of 17 with NH3/CH3CN gave a mixture of 4-amino-7-benzylpyrrolo [2,3-d] [1,2,3] triazine-5-carbonitrile (19) and 2-amino-1-benzylpyrrole-3,4-dicarbonitrile (21), A mechanism to account for the formation of this mixture is described along with studies on the effect that ammonia concentration and a TFA catalyst have on the product ratio. Compound 19 was converted into the 5-carboxamide and 5-thioamide derivatives of 19.

  Abstract The synthesis of N-1-substituted 2-nitropyrrole-3,4-dicarboxamides (4–5, 7–9) was accomplished from diethyl 2-nitropyrrole-3,4-dicarboxylate (2). 2-nitro-pyrrole-3,4-dicarboxamide (1) was prepared by deprotection of 2-nitro-1-[2-(2-pyridyl)ethyl]pyrrole-3,4-dicarboxamide (9). Compound 9 was obtained by two different methods.
